A trichromatic light emitting device has a substrate, multiple light emitting diodes (LED) and a red-light inducible phosphor layer. The substrate has a mounting surface. The LEDs have at least one green and at least one blue LED respectively emitting blue and green light along at least one output pathway and are mounted on the mounting surface of the substrate. The red-light inducible phosphor layer is disposed in the at least one output pathway and absorbs blue or green light to produce red light. Therefore, a white light is generated by mixing the blue green and red light. |
